Birch, Lexington, and Richard Briggs, Reading, Mass., assignors to Birch Brothers, Inc., Somerville, Mass., a corporation of Massachusetts Filed Jan. 22, 1962, Ser. No. 167,771 16 Claims. (Cl. 242-56) This invention relates to improvement in apparatus for f web winding wherein a continuous web of cloth or other sheet material is furnished from a source of supply and is wound about a cylindrical shell to obtain a roll of a predetermined size. The present application is a continuation-in-part of our co-pending application Serial No. 31,085 filed May 23, 1960, now Patent No. 3,047,248.

In the co-pending application noted above, we have disclosed a web winding machine of the three-roll type wherein a primary winding operation takes place on a rst and second roll and thereafter the partly wound roll is automatically transferred to a second and third roll where the secondary winding is completed. These winding operations are of a semi-automatic nature and are carried out with a special jaw mechanism including two sets 'of jaws which exert pressure during both the primary and secondary stages of winding. The two sets of jaws are controlled by lluid pressure devices and operate in a predetermined sequence so as to exert a downward pressure while becoming displaced vertically upwardly as the diameter of the cloth roll increases in each of the two stages of winding.

` The present invention is also concerned with a twoy.stage apparatus of web winding in which a three-roll type ofy web winding machine is employed and a jaw mechanism is employed :to exert substantially constant downward pressure, and a further objective of the invention is to carry out a continuous winding operation in a completely automatic fashion. The automatic winding process of the invention includes such steps as automatically feeding cloth winding shells into an operative position and mechanically lapping Ian end of cloth about the shell, applying a fresh shell against a partly wound roll to effect a transfer of the partly wound roll from one position to another, detecting the presence of seams in a web which is being wound, counting the yards of cloth which is being wound during a given period of time, and predetermining the size of a roll which is to be wound, together with the further steps of automatically cutting cloth and dofiing a completed roll.

The nature of the invention and its other objects and novel features will be more fully understood and appreciated from the following description of a preferred cmi bodiment of the invention selected for purposes of illus- Vtration and shown in the accompanying drawings in which:

In carrying out the invention, We have devised a method of winding which we refer to as a method of Robot Winding. The term, robot winding, is intended to deiine and include a method which is carried out automatically in all of its aspects other than at the point where cloth is first introduced into the machine and manually lapped'about the rst shell.

These automatic operations vinclude mechanically depositing shells in the jaw mechanism of the machine, em-

ploying a deposited shell to act as a transfer roll, automatically shifting a roll at a predetermined size from a primary winding position into a secondary winding position, measuring and cutting the cloth web at predetermined points to control the size of the roll and also to measure the total length of cloth handled and nally lapping ta cut end of cloth around a newly placed shell to repeat this cycle of operation in conjunction with a doffing operation.

The apparatus which we have devised for carrying out our method of robot winding is made up of three principal parts, including the cloth handling mechanism proper (FIGURES l to l0); electromechanical fluid pressure actuating devices builtinto or associated with the cloth handling mechanism shown schematically in FIGURE 11; and a separate control console in which are mounted various control devices which function as a robot brain for directing essentially all the movement of the cloth handling mechanism. The console includes a novel arrangement of counting devices, relays, and push buttons as illustrated in FIGURES 13 and 14.

A detailed description of the' cloth handling operations and the mechanism for carrying out these operations will first be described and thereafter the arrangement and functioning of the devices shown in FIGURES ll and l2 will be discussed in detail in connection with a typical operating cycle of the machine.

In one preferred form the robot winding method of the invention is based on the concept of maintaining on hand in a suitable magazine a supply of shells whereby successive shells may, at predetermined intervals, be automatically fed from the magazine into a primary winding position directly above a first winding drum. In combination with the magazine there is further provided novel seam detecting and counter mechanisms. The counter mechanism may be employed to control parts of the machine operation in a novel manner, and preferably includes a total yardage counter referred to as a lot counter, as well as two individual roll yardage counters -bers2 and 4.] f .t Y Y' The seam detecting apparatus is'located ashort dis-V tance away from the entering sidelof the frame as'shown at theY right hand side of FIGURE 3 and yguides-the web f `W valong a hcrizontal^path.'of travel to ajcounterhead generally denoted by the arrowCH.; '.1`heicpounte'r'head CHv is secured at' the enteringside of: the-, frame asshown .in'FIVGURESjs'r In detail .the .seam'detecting` apparatus consists jin a casing D1 in which ,issupport'edfar'oll D2 having jour-'V-l referred to as Ybatchj 'counte'rs, -and afpredetermining Y counter which may be presetforl a desired rollyardage.

Considering these parts more in detail, attention isdijaw mechanisms. y Also: secured between thefs'ides, 2 and 4 'are drivingi rollv shafts '6,' 6a' and .6b.Y on which, are

mountedvrespective drivingrollsY 8, 8a.. andSb. Thesey Trolls are actuated by motor driven sprocket chains 8c.

As illustrated in FIGURE:` 3,.'awebj of cloth `W furif Anished from `a suitable supply source, `is .led Vthrough a seamdetector D, then toa counterY deviceC, and' then. between-the' 'machinesides to atcylindrical shell -5.

VAt the -lower 'sider of vthe casing D1 areV roll stands D7 having roller arms D8 and D9 pivotally mounted therein. and Y resiliently supported byV springs as D11.: Small rolls D are rotatably received in the roller arms D8'and D9 and normally maintain thel contactsD12 andvD14 of a limit switch L2l in an open position as suggested in. FIGURE -5. When a seam in the`webW passes between kthe rolls DZVand D9,: the switch'y L2isV actuated as described in detailV at a later point in the specification.

The web of cloth W after'passing through the *seamy detector mechanism described, advances along a horizontal'path of travel to the counter head CH (FIGURE 3) which'includes a frame C, a guide roll C1 (FIGURE 10) and a measuring roll C2 mounted in frameC in rrolling contact with the guide roll C1. The counter head.

In this way an electrical' signal is transmitted topa multi-counter register. mechanism'whichl may, `for example, be mounted in a control console K as shown in FIG- URE 3 and. also FIGURES 13 and. 14. 'The 'multicounter register mechanism 'includes a lot counter C10,l two batch counters C8 and C9, and predetermining'` counter C11 as shown in FIGURES13 and 14. These devices are electrically connected as indicated in FIG- URE 16 so that a'yardage total is kept by the lot counter and alternateV counts aremade at the batch counters-for each roll of cloth .which 'is wound. Conventional means for resetting the batchY counters vare also provided.

As shown in FIGURE 6, the web W, after leaving the counter device, passes over the primary winding roll 8 and is wound around a shell 5.Vv This Y'maybe done.V

by hand lapping the edge of the'web about the shell when a winding operation is being initiated. vAt all other times it is carried outautomatically as hereinafter described.vr The shell -5 is-deposited in van operativevposi-l tion in themachine by means of novel shell feeding mechanism of the invention. Considering in greater detail this shell feeding, mechanism, vattention is directed to 5 .FIGURES 6, 9 and l0. Asfshownrthereim 'we provide at. the,v entering ,side 'of thefwinding machine, a shell magazine VM which',V may, Yforexa'mple, comprise an in clined hopper.

At itsupper side magazineiM is'forrned witha shelf fM4-which is: of asize adaptedto receive a shell; thereon and whichleads into` afdisc'hargefchute M5 constructed Ofa length 'generally corresponding to they length of `a shell and of a width slightly exceeding lthe shell` diamerter wherebya series of shells` M6,'M7, M8, M9 and .M10 may be loosely supportedone upon another-inthe position shown infFIGURESI6fandi10.

The closure platelthereby prevents shells-in the magazine chute kfrom dropping out during the loading operation.

VThe Ashell shown being rst deposited in the jaws by' theY transfer arms M in FIGURE l0, is denoted by the numeral 5.Y As shown in thislgure, the. shellvjournals have come into contactwith a` pair of lower Afirst jawsA and at this time a pair of upper rstjaws are maintainedi in a raised position to permit the shell journalsto be Y inserted., This lirstlset of jaws include a pair of spacedapartupper rollerY elements 9 and 11, and a set of lower "spaced-apartroller elements 9aand 11a. The spacing of 55 these rollers is vrsuchthat the shell journals may be rotat- -ably supported therebetween; o It. will be Lunderstood that-'the Vtransfer. armsn are elec- Atricallyl controlled as'hereinafterdescribed and ata se- 'lected pointreturn to the position of FIGURE 6 tor receive .another'shell' When thus retracted andV loaded with another shell, thetransfer arms may,` I nd, be employed to carry on a further function of `transferring a partly wound roll 'of cloth'fromf a primary winding position to a sec- Vondary windingpos'ition assuggested in FIGURE 9. Transfer in accordance with the invention is accomplished by electrically controlling the movement of the rst jaws and Huid pressure cylinders M15 in timed relationship -soV that the cylinders operate at a point after the jaws are opened and where a required period of windinghas been 70 accomplished in the qprimary winding position. -Atsuch a point the shell carried in the transfer arms is brought', into contact with the partly wound roll'and operates to transfer 'this'member from a primary winding position; into a secondary/'winding position4 as noted by the broken line showing of the partly wound roll in FIGURE 9.,

inafter described in detail.

ademas In the, position of shell 5, shown in FIGURE 10, it will be obseryed that the shell y is not in contact with the ydriving roll 8. In FIGURE 6 the shell 5 is shown lowered khas been carried out, the web has just been cut and a cut end of the web has lapped around a new shell.

To provide for the various changes in position of the shell 5, while at the same time exerting a yieldable downward pressure on the opposite journal portions of the shell 5, we support the first set of jaws for vertically sliding movement at opposite inner surfaces of the frame sides and we exert yieldable downward pressure by means of ,two fluid actuated cylinders 24 and 26 which are located externally of the frame' sides as shown in FIGURES 1 and 3. The fluid cylinders may, for example, be of the .pneumatically actuated type and are supported in an uprightk position with vertically reciprocating plunger extremities '24a and 26a occurring at the upper ends of the respective cylinders. A supply of compressed air is controlled by a solenoid S1 shown in FIGURE 1.

The plunger extremities 24a and 26a support connectf ing arms which extend through slots as 26b in the frame sides 2 and 4 to connect with vertically reciprocating bars at the inside of the respective frame sides 2 and 4. These bars are preferably constructed in the form of rack eler`rnents as shown in FIGURE 6 and one of them is denoted v by numeral 15. Channel means for guiding one of the rack elements is indicated at 17.

It will be understood that a similar rack and channel assembly is provided at the opposite frame side 2. Each ,of these rack elements has fixed thereto roller jaw supports as 9 in which are rotatably mounted upper roller jaws as 9 and 11 (FIGURE l0). When the cylinders 24 and 26 are actuated, these upper roller jaw supports,

l together with jaws 9 and 11, are caused to move up and down into different positions kof adjustment.

Immediately below the upper roller jaw supports 9 are .slidably supported lower roller jaw supports as 10 in fastened at their upper ends to respective projecting parts as 36 extending outwardly from the members 15. Similar l lower jaw structure is provided at the frame side 2.

By means of this arrangement the lower jaw supports ltl are resiliently held in contact with respective upper y jaw supports 9 to locate the two sets of jaws in suitably spaced relationship to receive and hold the journals of the shell 5 in a position such as that shown in FIGURE j 9. In this position the stops 9d are not engaged. However, by means of the arrangement described it will be observed, that each set of jaws 9, 11, 9a, 11a, may be raised as a unit until such time as the stops 9d engage Thereafter, the lower jaws will remain in a fixed position while the upper `jaws continue to rise to a desired point. 4It will he noted ythat upward movement of the upper jaws may occur either as a result of an increase in the size of the roll as winding proceeds, or it may be carried out by the cylinders v2,4 and 26. Operation of cylinders 24 and 26 by solenoid S1 may be manually controlled by switch P137, or by means of movement of a projecting part 36 against a limit switch L1 as suggested in FIGURE 10 and is here- Thus the first jaws will be disengaged when the partly wound roll reaches a predetermined size at which point part 36 engages limit switchl L1.

It will be apparent, therefore, that a definite sequence of steps may be caused, including the steps of locating the jaws in a raised position and in separated relationship to receive a shell; closing the jaws and lowering the shell into a winding position; yieldably supporting the shell against the driving roll as the roll diameter increases; stopping the lower jaws at one point in a loading position; disengaging the upper jaws when the roll is partly wound; and simultaneously transferring the partly wound roll into a secondary winding position.

In the open raised position of the jaws, when the machine is first being started up and a shell member has been inserted by the transfer arms the operationV of hand wrapping a cut end of cloth around rthe shell is carried out. In this raised position of the shell the stops 9d are engaged against the frame and the lower jaws can move no higher; also the upper jaws are raised to separate them from the lower jaws and define a space through which the shell spindles are free to move.

It is pointed out that the jaws will normally be located in a separated position with the shell occurring above the driving roll when the machine has been at rest and a winding operation is being started for the first time. The electromechanical means noted above actuates the pneumatic cylinders and locates the jaws and shell in a lowered starting position. Thereafter, a primary winding operation is carried out to form a partly wound roll as shown in broken lines in FIGURES 8 and l0, and also in full lines in FIGURE 9.

It will be seen that the shell handling apparatus now described, constitutes an improved and efficient means for carrying out a primary winding operation since a substantially uniform pressure may be exerted by means of the fluid cylinders as winding progresses and the roll diameter increases. In addition, the sequence of operations is especially advantageous in relation to two other steps which are next required in a continuous web winding cycle, including (a) transferring the partly wound roll W1 to a forward driving roll and cutting the web W when a fully wound roll is obtained and (b) inserting a new shell in the machine and mechanically. engaging a cut end of cloth about the newly inserted shell.

In accordance with the robot winding method of the invention, we next provide for automatically transferring the partly wound roll W1 onto rolls 8a and 8b by means of the shell feeding transfer arms M12 earlier described. This mechansm, as shown in FIGURE 9, engages a new shell M6 against the partly wound roll W1 and as the arms move forwardly transfers the roll W1 into the broken-line position indicated in FIGURE 9. The point at which the transfer arms and shell M6 are actuated, is controlled by the electrical circuit of FIGURE l2.

When the partly wound roll W1 is displaced by transfer arms M12 into a secondary winding position as indicated in FIGURE l0, for example, it will be observed that the web W extends across the rolls 8 and 3a and remains in this relative position until the roll W2 is fully wound. In this position the web is conveniently held for cutting and we provide a gate cutting mechanism which is located below the web W in the position noted. The cutting mechanism comprises a vertically reciprocating knife support 14 normally referred to as a gate structure located between the rolls 8 and 8a and having fixed thereto a knife 18. The knife 18 is normally supported in a position to lie below the driving rolls 8 and 8a as suggested in FIG- URES 6 and l0, and is adapted to be raised upwardly to cut the web W, as suggested in FIGURE 8, when a fully wound roll has been completed on the forward driving roll 8b. As shown n FIGURES 6, 9 and 10, opposite extremities of the gate structure 14 are guided in some suitable manner as by channel means 16 in the frame sides 2 and 4.

Movement of the knife support or gate is controlled through a fluid cylinder 2u which is in the fluid pressure actuating system of FIGURE l1, earlier described. The cylinder 20 is located in the base of the machine frame as shown in FIGURES 6 and l0 and at its upper end is secured centrally of the gate structure 14 by a fastening 20a.

` machine operation..

Theknife 1.8 is for-med of cutting sections 18a,'18b, 18e,

, etc., which are rigidly'secured `together as shown in FIG- 'URE 7, but any one of whichmay be detached when the machine is stopped for sharpening or replacementfb'yja ynew section. This is a highly desirable feature enabling .an operator to avoidlossof time in repairing a faulty knife without the entire machine having to'be taken apart. Frequent' sharpening of the'de'tached blade sections results in more positive cutting and no interruption of the We also construct the gate structure itself in avmanner to impart greater strength and resistance to flexing or bending. The body of the gate structure is formed as shown in v FIGURE 6 to constitute an elongated box lsection openV on one side, and arranged so that two=spaced apart side. portions are presented to .resist downward cutting prese sure. We find this arrangement resists any tendency for' bending or flexing to occur and' undesirable distortion isV avoided regardless of the kind of material'to be cut.

In combination with the gate Vstructure 14, we also proployed to lap a cut end of the weby W arounda newly inserted shell, as noted in FIGURE 8, and arefresiliently n tixed'to ashaf-t S by coiled springs and pivotall'yv contained in suitable bearings fixed tothe lower sectionr ofy `gatestructure 14. The coiled springs-anchored'to the gate normally seek to hold the fingers in an extendedposition against the roll 8 as shown in FIGURE 10. At their extremities'ethe fingers are formed with Ysmall bracket ypor'- tions in .which are mounted rollers j;

Vvide roller fingers-.F adaptedto bear'against roll l8 and i., best shown in FIGURES 6 and l0 and also indicated in a lapping position in FIGURE 8. These ngers are emj lare'secured by racks as 53 slidablyfreceived" hatopposite vsidesof the machine in channel ymembers as 54. y

The racks 53 are engaged with gears 56 fixed at opposite Vends ofashaft 58. A pair of pneumatic cylinders 604 and 62 located externally of the sides 2 and' 4 are connected throughV slots 61 (FIGURES)` in a manner similar to that of cylinders 24 and 26, to respective racks 53. `Thefcylinj ders 60 and 62 are alsovecontrolled through the solenoid S4 and relay R5 asshown in the circuit of FIGUREl 12, to raise the second jaws. When the cylinders are reversed, the jaws are lowered and come into register with and yieldablyrengage the journals of shell 5." Y v y VWindingy in the v'secondary winding position when the Aroll WZ issecured yby jaws50 and 52I takes place and fincludes adofling roll 80 which'islocatedfbetween the driving rollers 8av and 8b in a position tok engage an underside of the roll W2 in a position such as thart illustrated axis of rotation of the doflingroll 80 is arranged to lie The fingers F are constructed with an extended arc of v, -V

. curvature chosen such that eachof the rollers O'may, in a raised position ofthe gate, such as that shown in FIGURE' `l0, extend over. the peripheral surface of the shell'S to a point where overlapping-is positively insured.y We findv that by supporting theseroller fingers in a raised position *as described, we are enabled towrap la cloth end around the shell in a positive manner so that lapping is assured and failure to engage the cloth is avoided. Y

In FIGURES 6, 8 and 10, there is further illustrated improved mechanism for receivingthe partly wound roll W2 fromthe rear' drurn8 as it is transferred by Ythe, transfer arms M12.` Numerals 41 and 42 denote roll supporting arms rotatable on a shaft 43. v The end of arms 41 and 42 are pivotally attached to viluid cylindersr41a and 42a which are in turn anchored inside respective frame sides 2 and 4. The fluid cylinders 41a and 42a normally sup`v port the arms 41 and 42 in a position such as that Yshown in FIGURE 6.' In the position of FIGURE 6 the arms are adapted to yieldably receive the journals of a shell 5 and allow the partly wound roll to move gently into the secondary winding position without excessive shock.

FIGURE 7 shows the roll W2 moved into a forward position withthe shell'jou'rnals having been yretained bee` tween a pair of guider plates 70 and ,72- During the transfer of roll W2 into the secondary,winding'position, itwill be apparent that the'shelljournalsare disengagedand it is possible for the roll to become displacedr in an axial direction. To prevent this and'guide the roll properly, We provide the guide plates 70 andp72 and we further form these plates with flaring edges 70a and 72d. TheseV plates and their flaring edges are spaced such that the shell jour-V y nal extremities are necessarily caused to move into correct positions.

When the partly wound roll of cloth W2 has been guided by the arms 41 and 42'intoV a fully cradled posi-V tion between the rolls 8a and 8b, as indicated in broken lines in FIGURE 6, the shell journals are immediately engaged by a pair of upper second jaws earliernotedr The upper second jaws are also mounted at the inner sides of v the Ymembers 2 and 4. Each set of jaws consists of spaced j rollersasSt) and S2 secured onjaw supports as 50a which the machine.

YAs a result, when the doing roll is raised, the rollof cloth WV can move in one direction only, namely, outwardly of To raise .the dofting' roll 80, wemayr provide another pneumatic cylinder 82 mounted centrally in the base of the windingmachine as indicated in FIGURE6. This cylinder is attached-to a transverse member 84 of I'bearn section, for example. The I beam 84 has'its opposite eX- tremities slidably received in channe'lmembers as 861cm the inside of the frame sides .2; and 4 and the kdofiing roll.80 is connected to the beam extremities in vsome convenient manner. Y'

an electrical control circuit, as shownV in FIGURE 12, and hereafter noted'in detail. Movement of the dofling roll 80 upwardly is also employed to reset the arms 41. This is accomplished by means of cam portion formed along the edges of the arms 41 inV a manner such that as the cloning roll rises itengagesv the cam portion and forces the arm into an upright position,with tiuidV in the hydraulic cylinders 41a being reversed indirection of flow andpheld until the nextpartly'wound roll is received.

In addition to the :mechanical components now described,'the invention further includes a number of electri-ical control devccai,y including a 'i number .of limit Y switches, relays, solenoids and pushbutton type switches.

Some of Vthese devices are located in the machine and others are mountedin the separatecontrol console lK above-referred to and Vshown at the left hand side lof FIGURES. Y,

Animportant feature ofithese components and their arrangement, as'shown'in FIGURE l2, is thev provision for fully automatic operation'of all ofthe `circuits when so desired and yet-'each of the circuits may be manually actuated.

Considering in detail the various machineoperations kwhich are carried out with the aid of the above-noted eleotrical control devices,'it maybe assumed that the ma- Vvchine isbeing started up at thebeginning of a working period. The magazine' M is vloaded with shells, the nurn- H f. ber of yards Wanted in a.fully wound Aclothgroll is setiin the predeterminingjcounter .Cllby turning dialClla,

To operatethe dofing mechanism, we furtherrprovide and the main power switch PBS, as well as the automatic counter switch C14, are turned on.

Transfer load pushbutton switch P134 isthen closed thereby raising the first jaw to the loading position. Simultaneously, the shell feeding mechanism deposits a shell in the lower first jaws 9a and 11a. It is at this point that the machine operator manually laps an end of cloth around the shell as earlier described.

`First jaw down switch, PBS, is thereafter pressed which lowers the shell into contact with the first driving roll S. Winding commences and the control console takes over all further machine operations as noted below. When a predetermined size of roll has been wound, the limit switch L1 is actuated by the projection 36 and a circuit is closed energizing the relay R4 and solenoid S1 which causes the cylinders 24 and 26 to raise the first jaws into a fully opened position and the shell journals are released. Also initiated by closing of limit switch L1 is operation of a transfer load circuit in which there is a transfer relay R2 controlling a transfer solenoid S2. Relay R3 also operates a second jaw relay R5 controlling Varsecond jaw solenoid S4. The second yjaws are thus y.automatically raised into a position to receive the partly i wound roll and at the same time the transfer load mechanism automatically transfers the partly wound cloth roll from the first to the `second winding position and, at the same time, deposits a new shell in the first jaws.

A limit switch L holds the transfer-load circuit in operation until it is actuated bythe transfer arms at the end of the forward stroke. the transfer arm to a retracted position. Also provided is a transfer lock-out relay R1 to prevent adouble cycling of the transfer mechanism. The limit switch L4 when actuated by upper jaw releases the lockout.

The second jaws are designed to lower themselves after a time delay which is provided through a pair of relays R9 and R12. After the time delay noted, the jaws are auto matically lowered into engagement with the journals of the transferred roll, while the lower first jaws are maintained f ina raised position to support the newly deposited shell above and clear of the web travel line. It is pointed out that in typical windingoperations with which the present invention is concerned, the cloth may be furnished in lots of varying lengths some of which may cloth is completed, in some desired size, it is necessary to out the cloth and it is important to make the cut come as near as possible to a seam formed where two lengths of cloth have been sewed together. This prevents undue waste of cloth.

`It is a material `aid to-an operator to have the yards of cloth counted continuously as the cloth becomes wound in the machine. This is so for the reason that an operator can determine when the end of a lot is nearly at hand and this information can be communicated to operators of subsequent processing steps.

Finally, in addition to keeping a total yardage count realized from any given lot of cloth, it is desirable to keep separate measurements of the exact number of yards of cloth going into any given roll wound on the machine. Still f urther the counting operation as hereinafter described can provide for a predetermined size of roll being wound. In this latter case, by utilizing a seam detector combined in accordance with the invention, it becomes possible to make the cut occur near a seam. For example, if the counter for a predetermined size of roll to be wound is set to make approximately a thousand yard roll, the

L5 then operates to return 9 additional yardage involved in coming to a seam might be fty yards and thus the total yards in the roll would be a thousand and fifty yards.

Winding in the secondary winding position then proceeds and continues until the automatic counter reaches the preset yardage counter number. When this number is reached, the counter gives partial energization of the rst jaw down circuit and the cut circuit as shown in FIGURE 12. The first seam following the preset number being reached actuates limit switch L2 and completes the first jaw circuit to lower the first jaws and also completes the cut circuit to energize the cut relay R7. These circuits are shown in FIGURES l2 and 16. The counting mechanism includes a switching device shown in FIGURE 16, which device is defined to send an electrical signal to a standard type of electrical counter C11 which may, for example, be a counter of the type commonly referred to as a Veeder-Root counter manufactured and sold by Voeder-Root Inc. of Danvers, Massachusetts.

The switching device of FIGURE 16, also described elsewhere, consists of a one foot circumference measuring wheel C2 which rides against roller C1 as roller C1 is rotated by cloth passing into the winding machine. The one foot circumference wheel'CZ is connected to a pinion gear C7 which drives a spur gear C6 at a ratio of one revolution of gear C6 per three revolutions of gear C7 to give one actuation of the micro switch in FIGURE 15 for each yard of fabric which passes on roll C1.

The impulse generated by the micro switch of FIGURE 15 is transmitted to an electromagnetic counter C11, which essentially consists of two series of stepping switches of well-known type .C11a. C11a is the predetermining series of stepping switches which is preset before machine operation for the number of yards which are required in the cloth roll. C11b (FIGURE 14) is the indicating series of stepping switches which, when the numbers match the numbers on C1141, complete an operating circuit to close a relay and to permit an impulse from seam detector switch L2 to be passed to cut relays R7 and R11. These relays are then operated by the seam detector switch L2 when the next seam passes between roller D2 (FIGURE 3) and roller D10 to operate limit switch L2.

Basically, the function of counter C11 is to maintain the cutting circuit in a de-energized condition so that the seam detector switch L2 will not energize the cutting circuit until the preset yardage has been rolled onto the cloth roll. At that time counter C11 partially energizes the cutting circuit permitting the next operation of seam detector switch L2 to operate the cutting knife.

At the same time seam detector switch L2 de-energizes the first jaw circuit to lower the first jaws along with the shell into contact with the first winding drum for the cutting operation. It does this by breaking the holding circuit which has been holding first jaw relay R4 to main tain the first jaw and the shell in the raised position thereby preventing the shell from damaging severalk yards vof fabric by rotating against the fabric under pressure before the actual cut is made. When the rst jaws reach a down position, limit switch L7 allows current to pass from the cut relay R7 to Cut solenoid S3 to complete this circuit. The cutting mechanism then vrises and `severs the cloth. The cut circuit is also operated through the pushbutton switch P136 which, when closed, energizes relays R11, R7 and R8. R8 acts as a single pole double throw switch to reset the predetermining counter to zero. R11 operates to actuate switching relay R14 to switch from one batch counter to the other batch counter, and from a respective indicating light for the first batch counter to a respective indicating light for the second batch counter. R11 also activates R10 and R13 to place measured time delay in the operation of the doti mechanism. R11 also operates to break a holding circuit in the second jaw circuit to cause the second jaws to drop and grip the cloth roll in the second position if they are in the up position. This puts the roll under pressure and prevents the cloth from being pulled back when the knife meets' the minibus' ctig'asf a '1 safety circuit.' .R7," in addition to operating thelcut sole,
